Abstract (en)

[origin: EP3820109A1] This application provides a data transmission method and a related device. The method includes: A transmit end obtains indication information used to indicate that a first compressed packet is lost or fails to be decompressed. The transmit end sends a target original packet or a target compressed packet. The target compressed packet is generated by compressing the target original packet based on a preset compression parameter. The target original packet includes at least one of the following packets: a first original packet corresponding to the first compressed packet, and a second original packet corresponding to a second compressed packet compressed after the first compressed packet. The technical solution provided in this application can improve transmission efficiency that exists when a compressed packet is lost or fails to be decompressed.
